ScenariosScenarios ScenariosScenarios
• Three application areas: Telecommunication Car Problem Solving Service Enterprise IT
• Common in these scenarios is the need to create advanced services, based on service components from different actors.

• Use of UDDI registry to publish Semantic Web data for semantic-based description,discovery integration of web resources in a context of
needs of two research projects: “Adaptive Services Grid” (ASG) and “SmartResource”
ApproachApproachApproachApproach
• Mapping of RDFS upper concepts to UDDI data model using tModel structure, which makes possible to store semantically annotated resources internally in UDDI
• UDDI as an enabling specification for creation of a semantic registry for web resources in general
Semantic AnnotationSemantic AnnotationSemantic AnnotationSemantic Annotation
• A description of entities using Semantic Web standards
• A prerequisite to allow semantic discovering and integration.
• In the context of UDDI, an entity of the semantic annotation would be a Web Service and businesses, business services and technical information that is a target of a binding.
• Consider each resource entity (not just a web service) as a subject of the semantic annotation, registering, discovering, composition, enactment, integration, etc.

• A semantic search based on an externally created and operated matchmaker
• Semantic data are stored outside of UDDI a link from tModel of a Web Service in UDDI
to its Web Service Semantic Profile (WSSP). • WSSP serves as the semantic annotation of a
service and extends WSDL description of the service using RDF, RDFS, DAML+OIL or OWL, RDF-RuleML

ConclusionsConclusionsConclusionsConclusions
• UDDI has enough support for the registration of semantically annotated resources
• SmartResource project can use UDDI to implement Notice Boards for registering semantically annotated resources
• Publishing ASG service and domain ontology to UDDI can be performed based on publishing of WSMO to UDDI
• Have to elaborate API to support semantic discovery of registered resources
• Navigable structure
Future WorkFuture WorkFuture WorkFuture Work
• Further research is needed to elaborate semantic discovery algorithms and UDDI APIs based on proposed way of storing semantics in UDDI
